How to solve error ""cannot instantiate the type Triple""

问题

我尝试使用三元组来返回多个值,但出现了“无法实例化类型Triple”的错误。我尝试了多种方法,但都没有成功。正确的语法是什么?

import org.apache.commons.lang3.tuple.Triple;

private static Triple<String, String, String> test() {
    Triple<String, String, String> triple = Triple.of(null, null, null);
    // ...
    return triple;
}
英文:

I'm trying to use a triple to return multiple values but I get "cannot instantiate the type Triple" I tried multiple things but nothing worked. What is the correct Syntax?

import org.apache.commons.lang3.tuple.Triple;

private static Triple&lt;String, String, String&gt; test() {
	Triple&lt;String, String, String&gt; triple = new Triple&lt;&gt;();
	...
	return triple;
}

Triple是抽象的,请使用MutableTriple或ImmutableTriple代替。

英文:

Triple is abstract, use MutableTriple or ImmutableTriple instead.
